rlhis invention `is an improvement in or modification of the*inventiondescribed lin my Patent No. 1,891,129, granted Dec.- 13, 1932. e, y e

In the specification of Lsuch prior application, I have described cokeextracting means comprising a coke chamber lixedbeneath aV retort toform a continuous chamber therewithand having an lopening at its lowerend, a table movable inthe coke chamber, a rear inclined wall of thecoke chamber, a false back tiltablertowards the inclined wall tofacilitate coke discharge from' the coke chamber, an enclosedshutter forcutting oli the retort from the coke chamber, and a door for sealing theopening at the lower end of the coke chamber.

According` to present invention, l do away with the table which in myprior application was movable in the coke extractor chamber, and arrangethe plant so that it Works intermittently, that is to say, after aperiod of carbonization in the retort the shutter which separates theretort from its coke extractor chamber is withdrawn, so as to allow thecoke to fall into the coke eX- tractor chamber.

Steaming of the coke with cooling of the latter then takes place, andwhen this has been carried. to the desired stage, the shutter is closedacross the top of the. coke chamber so as to separate the latter fromthe retort and simultaneously the coke chamber is enlarged by thetilting of its inclinable wall. The door upon the coke chamber can thenbe opened and the coke discharged. The retort is again filled andcarbonization carried on as before.

With this arrangement, it will be seen that the coke chamber is filledimmediately the shutter is withdrawn, and there is not that slow fillingof the coke chamber which occurs with the arrangement described in mypatent.

I provide means at a short distance above the discharge door of the cokeextractor chamber to hold up the charge in the coke eX- tractor chamberwhilst the latter is being lilled from the retort. When the holding upmeans are withdrawn, they allow a short descent voi: the r.completevCharge the coke `chamber andthe retort before the discharge door isactually,opened; The attendant can then ascertain from such shortdescent that the coal which lis in a sticky ortenacious condition at thetop of the retort,is'free and not adhering to the retort walls, and maypoke it yround .to release it before a new charge is introduced. j

It will be understood that the arrangement of .the coke extractorchamber with its movable wall andwith the shutter, may b e the saine, asaredescribed in my prior Patent No. `1,891,129. i

:Referring to the' accompanying eXplanatory drawings Figure 1 is asectional elevation showing 4coke extracting means arranged inaccordance witht my present invention, the parts being in the positionsthey occupy after carbonization and during steaming and prior to cokedischarge.

Figure 2 is a view similar to Figure 1, but showing coke dischargetaking place.

The bottom of the retort to which the coke chamber is attached is shownat a, and the coke chamber at b. The shutter for cutting olin the retortfrom the coke chamber is indicated at c and the door which permits oficoke discharge from the bottom of the coke chamber at d. The tiltablewall of the coke chamber is indicated at e and the space into which itmoves to enlarge such chamber when coke discharge is to take place isshown at The wall e is ulcrumed at el and is interconnected with theshutter c.

yThere is a hinged Hap g at the base of the coke chamber which in itsservice position holds up the coke charge and prevents itsir bearingupon the door d as shown in Figure 1. The flap g when turned into itsout-ofservice position as shown in Figure 2 lies in a recessed part ofthe coke chamber wall so as not to obstruct the free discharge of cokefrom the said chamber.

Assuming that carbonization of the charge in the retort has beencompleted and that the lower part of the carbonized charge has beenallowed to fall into the coke chamber,- the parts will be in thepositions shown in Figure l, the shutter 0 being open, the flap gobstructing the descent of the coke charge on to the door cl, and thewall e in line with the retort wall above. Steaming of the coke chargein the chamber b can now take place. The charge is now in condition fordischarge. The Hap g is iirst moved into the out-of-service position inFigure 2, which should permit the charge to fall on to the door d. Theattendant makes an observation toV see if the coal at the top of theretort has fallen and if not he pokes round it to release it. Theshutter c is now moved to the position shown in Figure 2 to cut off thematerial in the retort from. the material in the coke chamber andsimultaneously the wall e is moved to the position shown in Figure 2 toenlarge the coke chamber. When the door d is now opened, the chargefalls freely out of the coke chamber along the side d1 of the door.

After discharge is completed and theretort has been re-charged and thenew charge carbonized, the parts are returned to the positions shown inFigure l, and the cycle of operations repeated.

What I claim is l. The combination with a vertical carbonization retort,of an unobstructed coke chamber fixed beneath said retort to form acontinuous chamber therewith and having an opening at its lower end, arear inclined wall of said coke chamber, a false back tiltable towardssaid inclined wall to facilitate coke discharge from said coke chamber,an enclosed shutter for cutting off said retort from said coke chamber,and a door for sealing said opening at the lower end of said cokechamber.

2. The combination with a vertical carbonization retort, of anunobstructed coke chamber fixed beneath said retort to form a continuouschamber therewith and having an opening at its lower end, a rearinclined wall of said coke chamber, a false back tilt-able towards saidinclined wall to facilitate coke discharge from said coke chamber, ashutter provided on'said alse back for cutting off said coke chamberfrom said retort when said false back is tilted, and a door for sealingsaid opening at the lower end of said coke chamber.

3.`The combination with a vertical carbonization retort, of anunobstructed coke chamber fixed beneath said retort to form a continuouschamber therewith and having an opening at its lower end, a rearinclined wall of said coke chamber, a false back tiltable towards saidinclined wall to facilitate coke discharge from said coke chamber, anenclosed shutter for cutting off said retort from said coke chamber, adoor for sealing said opening at the lower end of said coke chamber, andcoke hold-up means in said coke chamber above said door movable clear ofthe path of the coke during discharge of coke from said coke chamber.

In testimony whereof I have signed my name to this specification.

ERNEST WEST.
